Hepatatone Plus also contains N-Acetyl-Cysteine (NAC), a derivative of the amino acid cysteine, which possesses powerful antioxidant and liver-protective actions. In addition to protecting the body from oxidative damage, NAC up-regulates the formation of glutathione, the predominant antioxidant found in the liver. Glutathione depletion can be a significant complicating factor in liver disease pathology.
